GBPJPY’s 168 or gold’s 1680? I have been studying #WD Gann trading methodology for >15 years from his early astrology trading to later GANN Square.. BUT “both” are very “subjective” even his later Work of Gann Square more “practical” than astronomy method. Back to my “origin” maybe I should study more about Chinese’s Ancient Wisdoms where I found Chinese metaphysic/ 5 elements yin/yang harmony trading are more “practical” even as simple 168 numbers “stored” “prosperous energy”...p/s..From net : It is a little known fact that W. D. Gann went to India and studied Indian Sidereal Astrology. In his notebooks we find sketches of astrological symbols on his charts; and in his memoirs, he discusses his journey to India. In fact, the famous Gann wheel was first used by tea merchants in seventeenth century India..
